Hi guys,i could do with a little clarity on installing a wet roomsystem.I have an older propety with a concrete floor to do.I have done 2 floors before using different systems,tile safe & bal WP1.As the customer wants UFH i was purposing using 10mm Marmox & a tray former. The query is,if i use lastogum as the tanking does it go above or below the marmox,& if below does the tray need tanking.I spoke to a UFH supplier & they put marmox first,then UFH & then self levelling screed & then lastogum & finally tiles!Is that right or is there another way.Your thoughts would be much appreciated.Regards Topgun
